Dlink DGS-3100 / DGS-3120 support
by Bruno Galindro da Costa 21 Mar '13

21 Mar '13

Hi! Is Dlink DGS-3100 / DGS-3120 supported by NAV? If yes, why these errors are ocurring with ipdevpoll module? 2013-03-19 19:52:09,257 [WARNING plugins.typeoid.typeoid] [inventory 10.10.25.110] Netbox has changed type from unknown to unknown (sysObjectID 1.3.6.1.4.1.171.10.94.3) 2013-03-19 19:52:30,376 [ERROR jobs.jobhandler] [inventory 10.10.25.110 Job 'inventory' for 10.10.25.110 aborted: ('Job aborted due to plugin failure', TimeoutError('',)) 2013-03-19 19:54:49,507 [ERROR jobs.jobhandler] [linkcheck 10.10.25.110] Job 'linkcheck' for 10.10.25.110 aborted: ('Job aborted due to plugin failure', TimeoutError('',)) Is there a way to put ipdevpoll module in debug mode to see what is happening with more details? The device is correctly configured with snmpv2c. See it: # snmpwalk -v2c -c public 10.10.25.110 .1.3.6.1.2.1.2.2.1.2.40 iso.3.6.1.2.1.2.2.1.2.40 = STRING: "Ethernet Interface" That command was executed from the same VM that NAV is installed. I have another two monitored devices: Dlink DES-3028P and Dlink DES-3526. These two are correctly functional in NAV and those snmp configurations are set in the same way of Dlink DGS-3100. -- Att.

Re: Netmap broken in 3.14.1

Found the fix for netmap at https://nav.uninett.no/hg/stable/rev/9d9b0b8670da and manually applied it to backbone.html. Still looking into the geomap configuration.

Announcement: NAV 3.14.1 released
by Morten Brekkevold 08 Mar '13

08 Mar '13

Just a week shy of Pi Day, we bring you a new NAV feature release: NAV 3.14.1 is now available for download at Launchpad: https://launchpad.net/nav/3.14/3.14.1 The 3.14.1 release adds the following user-visible features and improvements: * NAV now fully supports SNMP communication over IPv6. Please see the release notes for more information. * Most of the service monitor plugins now support IPv6. * NAV documentation is slowly moving out of the wiki and into Sphinx. Now, every NAV installation includes a link from the front page to the browseable, locally installed documentation. * The Toolbox can now be collapsed into an icon/title-based list if the tool descriptions aren't needed or wanted. * The ordering of tools in the Toolbox can now be customized individually by each user. * The status page and portadmin have been adapted to work well on small screens/mobile devices. * Portadmin now supports editing trunks. * Portadmin includes a new feature to enable trunking of predefined voice VLANs on access ports, for SIP phones that support 802.1Q trunking And contains fixes for these reported issues: * LP#483534 (Subnet Matrix: Display description of prefix in dropdown) * LP#736818 (Reorganise toolbox webpage) * LP#965144 (Front page needs link to Status page) * LP#1060976 (Portadmin imports nav.Snmp.pysnmp_se directly) * LP#1062206 (Camlogger should log entries from non-access ports if connected device is not a networking device) * LP#1062317 (Support SNMP over IPv6) * LP#1062318 (Servicemon plugins should be reviewed for IPv6 support) * LP#1069770 (Want a mobile version of the status page) * LP#1069771 (Want a mobile version of port admin) * LP#1092154 (Portadmin crash when unicode characters in ifalias) * LP#1092156 (Portadmin crash when it cannot find a netbox by name or ip,- and interface by id) * LP#1092551 (Bug in threshold, crashes when searching for netboxes * LP#1103376 (portadmin should highlight changes in a better way) * LP#1134390 (Machine tracker crashes when inputting non-ASCII characters in search) * LP#1134392 (Invalid IP search patterns cause abnormal Machine Tracker behavior) * LP#1135699 (arnold fails to open quarantined ports on cisco devices) * LP#1137799 (cricket runs eval on config that contains curly braces) * LP#1143962 (Device history search for location crashes) * LP#1146602 (Maintengine TypeError crash) * LP#1146604 (arnold lacks links to relevant information) Please report bugs at https://launchpad.net/nav/+filebug :-) Binary packages for Debian will be made available as soon as possible.

Warning from eventengine - topology problem
by Ingeborg Hellemo 20 Feb '13

20 Feb '13

NAV 3.13.0 Eventengine logs a lot of topology problems of two kinds. One regarding the NAV-server itself: 2013-02-18 11:23:37,173 [WARNING nav.eventengine.topology] NAVServer('129.242.5.182') topology problem: router ma-gsw3.infra is up, but not in VLAN graph for <Prefix: 129.242.5.0/24 (vlan 103 (nett,srv,5-nettet))>. Defaulting to 'reachable' status. The other kind regarding some (but not all) random devices: 2013-02-18 11:23:37,740 [WARNING nav.eventengine.topology] nfh-b100-nc.prn topology problem: router nfh-gsw.infra is up, but not in VLAN graph for <Prefix: 10.253.19.0/24 (vlan 600 (uit,prn))>. Defaulting to 'reachable' status. Is there anything we can do to in our setup to eliminate the warnings (except changing the debug level...)? --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

We are running NAV 3.13.0 since 08.02.13 Some days ago something happened in our environment that caused eventengine to throw an error: 2013-02-13 17:08:57,887 [ERROR nav.eventengine.engine] Unhandled exception in plugin <nav.eventengine.plugins.boxstate.BoxStateHandler object at 0x804e170d0> ; ignoring it Traceback (most recent call last): File "/usr/local/nav/lib/python/nav/eventengine/engine.py", line 190, in handle_event handler.handle() File "/usr/local/nav/lib/python/nav/eventengine/plugins/delayedstate.py", line 52, in handle return self._handle_start() File "/usr/local/nav/lib/python/nav/eventengine/plugins/delayedstate.py", line 68, in _handle_start self._set_internal_state_down() File "/usr/local/nav/lib/python/nav/eventengine/plugins/boxstate.py", line 29, in _set_internal_state_down shadow = self._verify_shadow() File "/usr/local/nav/lib/python/nav/eventengine/plugins/delayedstate.py", line 189, in _verify_shadow netbox.up = (Netbox.UP_DOWN if netbox_appears_reachable(netbox) File "/usr/local/nav/lib/python/nav/eventengine/topology.py", line 32, in netbox_appears_reachable target_path = get_path_to_netbox(netbox) File "/usr/local/nav/lib/python/nav/eventengine/topology.py", line 82, in get_path_to_netbox path = networkx.shortest_path(graph, netbox, router) File "/usr/local/lib/python2.7/site-packages/networkx-1.6-py2.7.egg/networkx/ algorithms/shortest_paths/generic.py", line 124, in shortest_path paths=nx.bidirectional_shortest_path(G,source,target) File "/usr/local/lib/python2.7/site-packages/networkx-1.6-py2.7.egg/networkx/ algorithms/shortest_paths/unweighted.py", line 138, in bidirectional_shortest_path results=_bidirectional_pred_succ(G,source,target) File "/usr/local/lib/python2.7/site-packages/networkx-1.6-py2.7.egg/networkx/ algorithms/shortest_paths/unweighted.py", line 205, in _bidirectional_pred_succ raise nx.NetworkXNoPath("No path between %s and %s." % (source, target)) NetworkXNoPath: No path between <server> and <router> This happened for 5 servers all on the same GSW. Four days later 4 of them are still marked as down even though ipdevinfo reports availability numbers like the following and the servers clearly are up: Availability 100.00% last day, 99.77% last week, 99.94% last month Where do I have to push (or kick) to make NAV recognise the servers as up? --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

Announcement: NAV 3.13.0 final released
by Morten Brekkevold 07 Feb '13

07 Feb '13

A beta version of the next NAV feature release, version 3.13.0b1, is now available for download at Launchpad: https://launchpad.net/nav/3.13/3.13.0b1 The 3.13.0b1 release adds the following user-visible features and improvements: * The eventEngine has been rewritten to Python. This was the last remaining Java component of NAV, meaning Java is no longer needed for installing and running NAV. * VLANs are now searchable from the Navbar. * IPv4, IPv6 and MAC host counts for each VLAN is now graphed over time. * NAV is now able to detect and graph data from sensors on Cisco Nexus devices. * Maintenance tasks can now be configured to end automatically when all components involved in the task are up. * IP Devices that are down can be placed on immediate maintenance until up again directly from the status page. * Subscriptions to MAC address prefixes are now possible in Macwatch. Use with caution! And contains fixes for these reported issues: * LP#305435 (Sort by "Start time" or "End time" in machinetracker) * LP#305441 (Button for "Put on maintenance immediately") * LP#317800 (Color gradient to express utilization of IPv6 subnets) * LP#341703 (Manual detention does not pursue client) * LP#361530 (Arnold: Predefined detention does not exponentially increase detentions) * LP#744932 (Arnold should give warning if snmp write is not configured) * LP#833959 (make install overwrites nav.conf and db.conf) * LP#922793 (Possibility to set end time = "until device is up again " in maintenance) * LP#961097 (Don't list cancelled maintenance tasks in active list) * LP#961100 (Show component details in maintenance task list when there is only a single component) * LP#1057509 (Mouseovers with number of active IPv6 addresses in Subnet Matrix) * LP#1057511 (Get sensor information from CISCO-ENTITY-SENSOR-MIB) * LP#1062130 (NAV should graph IP address usage per prefix) * LP#1069773 (macwatch should be able to look for MAC address prefixes too) Remember, this is still beta status, and should not necessarily be considered production ready. 3.13 features two major rewrites, one for the eventengine one for the port blocker, Arnold. If you want to help us test the beta version, you are most welcome. Don't forget to check out the release notes, and please report bugs at https://launchpad.net/nav/+filebug :-) Binary packages for Debian will be made available as soon as possible.
